Helen is a primary school teacher and principal in Cork.
She's strongly advising parents against planning any holidays for September:
'The prices have come down so much on holidays on the 1st of September.'
'Parents could be tempted to go on their sun holiday then or abroad as a family.'
'I believe that all children should be back in school at the beginning of the school year.'
'September is really a settling in month.'
